There is a Wheelwright shop at "The Ford" (Used to be called Greenfield Village) in Dearborn Michigan. The complex is an amazing display, a living museum if you will, of Americana. It includes the Orville and Wilbur Wright house, Edison's Menlo Park lab, taken apart and put back together piece by piece. Working shops...Tin shop, print shop, glass and pottery, and yes Wheelwrights....
They don't work on such large stuff as above but they do maintain and "rewheel and tire" the horse drawn wagons that supply and transport people throughout the "Village". It is amazing to watch them work, with period tools and methods.
